When airplane engine starters fail to work, a truck is often used as an emergency starter at the U. S. Naval Reserve aviation base at Floyd Bennett field. A twenty-five foot cable rope fastened to the truck’s rear bumper is attached to a special “mitten” that slips over the propeller blade. To spin the propeller and thus turn the engine over, the truck pulls ahead quickly and the mitten slides off the propeller tip at the end of the tug.
